[GiNaC-list] archive/unarchive on functions with a variable number of arguments

[Vladimir V. Kisil]

	Dear Richard,

	Thanks for properly fixing it. Looking into the matter I also
  was not able to understand LaTeX printing routine for zeta with two
  parameters: it outputs \zeta(10) for zeta(10,x). But as I
  said, I am not familiar with zeta with two arguments to judge the
  situation.

  Best wishes,
  Vladimir
